meeting 2026 01 13 gw - JacobPilawa/TriaxSchwarzschild_wiki_6 GitHub Wiki

Context

• In addressing some of the open questions from the meeting, I discovered that I had the W1 k-correction computed incorrectly, and had been dividing where I should have been multiplying.
  • More specifically, in Section 5.1 of the J23 paper, they state that the flux gets "boosted" by a factor, which I intpreted as dividing by the factor they give, when it should have been multiplied.
• I have verified that the W1-W2 k-correction is correct, however, so the only change needed is to fix this W1 k-correction. This bullet tries to bring the past few bullets up to speed and assess where we are at now.

Diagnostics

• Here are two sanity plots showing that the updated k-correction is being done properly.
